Explanation / Answer

Methods.java

import java.util.Arrays;

public class Methods {

public static void main(String[] args) {

int arr[] = {1,2,3,4,5};

evensToZero(arr);

int a[][] = {{1,2,3,10},{30,20}};

System.out.println("Sum: "+sumOfTens(a));

}

public static void evensToZero(int[] arr) {

for(int i=0;i<arr.length;i++) {

if(arr[i] % 2 == 0)

arr[i]= 0;

}

System.out.println("Array elements: ");

System.out.println(Arrays.toString(arr));

}

public static int sumOfTens(int[][] arr) {

int sum = 0;

for(int i=0;i<arr.length;i++) {

for(int j=0;j<arr[i].length;j++) {

if(arr[i][j] % 10 == 0)

sum+=arr[i][j];

}

}

return sum;

}

}

Output:

Array elements:
[1, 0, 3, 0, 5]
Sum: 60
